IMPROVEMENT lN COMBINED LAND-ROLLER AND CLOD-CRUSHER.

Specification forming part of Letters Patent No. 223,125, dated December30, 1879 application filed November 8, 1879.

To all whom it may concern:

Be it known that I, STEPHEN J. FISHER, of East Pleasant, in the countyof Kosciusko and State of Indiana, have invented a new and valuableImprovement in Combined Land- Roller and (Hod-Crusher; and I do herebydeclare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side view of myimproved land-roller and clod-crusher, and Fig. 2 is a top view of thesame.

This invention has relation to means for crushing clods and pulverizinglumpy soil; and it consists in the construction and novel arrangement ofthe eight-square rollers following each other in sets of three, saidrollers being journaled in boxes which are let into recesses in thebeams of the frame and bolted thereto, as hereinafter shown anddescribed.

In the accompanying drawings, the letter A designates the frame of theland-roller, consisting of two side beams, a, and one middle transversebeams 0, the ends of which are. mortised into the side beams, and thecentral portions of which are mortised to receive the tenoned ends ofthe middle beam.

B indicates the rollers, which are made eight-square or octagonal inform, as shown, and are arranged in sets of three following each otheron each side of the middle beam, b. Each roller is provided with strongjournals d at its ends, which are seated in boxes 6,

which are let into recesses g in the side and middle beams, and securedby means of strong bolts 71 which pass up through the boxes and beams,and are fastened by nuts is on the upper edges of the latter.

The object of these rollers is to break up the clods by successivemashing blows from angular and flattened surfaces, the former having abreakingaction and the latter a pulverizing effect, the eflici'ency ofthe rollers being rendered complete by arranging them in sets of threeon each side of the middle beam, and thereby separating each two rollerswhich are in line with each other, so as to allow the eight corners ofeach roller full play. By letting the boxes of the roller-journals intothe beam they are strongly secured in place, and are not liable to bedisarranged or loosened by the rough action of the angular rollers.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s

The clod crusher and pulverizer herein described, consisting of therectangular frame having the middle beam, 1), and side beams, a, theeight-square rollers B, arranged three on each side of the middle beamfollowing each other and journaled .in boxes 0, let into the under edgesof said beams, and bolted thereto by through-bolts h, as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

STEPHEN J. FISHER.
